A few years back Cary had a presentation that I feel like woke the council up to the fact that bedroom communities (high ratio of low-density residential to commercial/industrial) that are landlocked (can’t sprawl any more) are doomed to either have very high property taxes, or have to deal with declining services and infrastructure.
We talked about it a bit here.
Anyway that preso really seemed to wake the town council up to the need for denser development, and ever since then, I have seldom seen them turn one down.
